For a complete understanding oi my invention, reference is to be had tothe following descrip- :tion and accompanying drawing. in which Figure 1is a vertical sectional view illustrating a hair drier constructed inaccordance with my invention.

Figure 2 is a sectional view taken on the line 't-i of Figure 1.

Referring in detail to the drawing, the numeral i indicates a casingdivided into chambers 2 and t. A fan il of any desired character ismounted in the chamber 3, the outlet of which ls indicated by thecharacter h and extends into the chamber t so that air is taken from thechamber t and forced into the chamber 2 and escapes therefrom by a pipet. A flexible hose 'l is connected to the pipe t and has connectedthereto a hood or nozzle t capable of fitting over a persons head. Adamper or valve t is located in the pipe t and may be adjusted forregulating the flow of air from the chamber 2 to the hood t. A vent pipeit communicates with the chamber i and with the atmosphere and has agate valve il which may be readily adjusted into open and closedposition.

Carried by the hood 8 and of 'a shape similar to the latter is a casingi2 dening between itself and the hood t an air passage i3 having anoutlet nipple lli to which is connected' a flexible pipe l5. The otherend of the flexible pipe is connected to a hood i6 arranged incommunication with the chamber 3. A lter l l is placed between the hoodit and the interior of the chamber d. The hood also is equipped with agate valve it which may be opened to establish communication between theatmosphere and the interior of the hood it.

l'I'he filter l'l may be of any desired construction and of any suitablematerial. The' casing i2 l projects slightly beyond the dischargeopening of (El. 34u26) a persons head may p therefrom through thepassage ld and pipe it to the chamber t by the suction of the fan il.The air on passing into the chamber t is hltered so that foreign matteris removed therefrom before being expelled into the chamber t.

Arranged in the chamber 2 is an absorbent bed it for the air to contactwith during movement to the chamber 2 from the chamber t to the pipe d.Any desired material may be employed in the ccnstruction of theabsorbent bed which acts to re move from the air moisture so that theair de-` livered to thev persons head by the hood t will have itsmoisture content lowered to a minimum. A cooling coll il@ is located inthe pipe d over which the air from the chamber t must pass on its way tothe hood t. e cooling coil acts to lower` the temperature of the air andit is preferable that this air be oi a temperature ci substantiallyblood heat so that the air contacting the head of the person will be oi'substantially the same temperature as or the person to free the personof discomfort either from air of too high or too low a temperature. Theair also having its moisture content reduced to a tot.: by the absorbingbed it will more thoroughly and quickly dry the hair of a person.

A cooling coil tt may be arranged in the absorbent bed id for thepurpose oi lowering its temperature. The cooling coils dit and tti maybe cooled in any well known manner.

After the device has been in use for a period of time, the absorbent bedmust be freed' of the moisture collected and to accomplish this aheatlng device't'i of any desired construction is arranged in thechamber t and may or maynot be therrnosta'tically controlled andautomatically lighted or extinguished. rlhe heating device will rapidlydry the absorbent bed of moisture and during this operation the gatevalve d is closed and the gate valve i i is opened so that the dryingair may pass to the atmosphere.

During the use of the device for the purpose of drying hair should it bedesirable to obtain air to the chamber d directly from the atmosphere,the gate valve it may be opened.

Having described the invention. I c

A hair drier comprising a casing having a vertically arranged chamberand a fan chamber connecting with the lower end of the vertcal'chamber,said vertical chamber having opposed outlets adjacent the upper endsthereof. valves for controlling s-aid outlets, a head engaging meansconnected to one of said outlets, means connecting said head engagingmeans to the fan chamber,

chamber and each including connected parallel portions to intercept theair passing through the vertical chamber. and cooling coils extendingsubstantially the full lengths of the absorbent beds and embeddedtherein.
